Comparison of color constancy methods for skin color under colored illuminants

This paper considers well-known color constancy methods for recovering and detecting skin color - the methods are compared by using the facial images with various skin colors acquired under colored illuminants. For quantitative evaluation, we created the experimental images based on the Caltech Face Database and used standard deviation on their Cb-Cr histograms as an evaluation factor. The experimental results showed that the color constancy method can be used to reduce the effects of colored illuminant and color difference in skin regions caused by the colored illuminant is reduced by GW method.
